S81.01Laceration without foreign body of knee

S81.01 is the ICD-10-CM diagnosis code for laceration without foreign body of knee. It belongs to category S81 (open wound of knee and lower leg), block S80-S89 (injuries to the knee and lower leg) and chapter 19 (injury, poisoning and certain other consequences of external causes). It is a header code, so it can't be reported by itself; one of its 3 subcodes must be used instead.

Within S81.0, choose S81.01 (Laceration without foreign body of knee) only when documentation doesn't support a more specific option: unspecified open wound of knee (S81.00), laceration with foreign body of knee (S81.02), puncture wound without foreign body of knee (S81.03), puncture wound with foreign body of knee (S81.04) and open bite of knee (S81.05).

Codes in this range require a 7th character: A for initial encounter, D for subsequent encounter and S for sequela. Use placeholder "X" characters to fill any empty positions before the 7th character.

It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.
